Nagios 3.x capability to display multiple lines of plugin output.
It calls multiple child plugins and displays their output in the
long_plugin_output. A summary is given in the standard plugin output.
The child return code with the highest severity becomes the parent
(check_multi) plugin return code.
The configuration is very simple: a NRPE-stylish config file contains
a tag for each child plugin and then the check command line.
check_multi can cover complex Business Process Views - using a builtin
state evaluation mechanism. The second benefit is cluster monitoring
with no need for extra services. All you need is provided by check_multi.
